WASHING-MACHINE.

Specification of Letters Patent.

Patented Mar. 17, 1914.

Application filed August 8, 1911. Serial No. 642,992.

To all whom it may concern Be it known that I, LOUIS JUDELSON, a citizen of the United States of America, residing at 159 West lwenty-fourth street. New York city, in the county and State of New York, have inventedcertain new and useful Improvements in \Vashing-Machincs, of which the following is a specification.

My invention relates to improvements in washing machines of the type employing an outer casing, and an inner, perforated, revoluble, cylinder wherein the articles to be washed are alternately rotated in one direction, and in the other while being sub jected to the action'of wet steam. The outer casing and inner cylinder are usually constructed of copper as the material most suitable for the purpose, and heretofore the outer cylinder has been in the form of a drum open at bothends and having a header of cast iron or like material closing each of the ends. One of the disadvantages in a construction of the kind referred to is that when it is necessary to repair the outer casing, either or both the iron headers must be taken out, resulting practically in a disruption of the casing, inasmuch as the headers are firmly riveted to the latter. Another disadvantage is found in the fact that when leaks develop between the copper casing and the iron headers, it is impossible to use solder to repair these leaks as the metals to be soldered together are unlike. A further disadvantage in the constructions heretofore employed has been the practical impossibility of providing an outer casing which would effectually prevent the leakage of steam therefrom.

The object of my invention is to provide a Washing machine wherein the several disadvantages above referred to as inhering in present structures are obviated, which improved washing machine may be readily assembled and disassembled and wherein the outer casing is proof against lealrage of steam.

The preferred form of the invention is illustratively exemplified in the accompanying drawing, wherein Figure 1 is a side elevational view of my improved washin machine, the cover being closed down on t e outer casing; Fig. 2 is an end elevation of Fig. 1 looking toward the right; Fig. 3 is a cross sectional view taken on the line 3-3 of Fig. 1, representing the cover partly open; and Fig. 4: is a in carrying my invention into practice I preferably form the outer casing as a complete drum, that is to say, it consists of the body portion 1 the end members 11 and the sliding cover 12 all of like metal such as copper. To prevent leakage of steam between the easing and end members, I preferably form the joint thcrebctwecn as shown in Fig. 1 from which it will be noted that the material of the body portion 10 is bent upon itself to form the overlapping members 10* and 10, and each end member 11 1s provided with the lap 11. Interlocking each end member ll with the body portion of the casing is a separate locking member which comprises the web portion 13, the overlapping flange members l3 and 13" which engage the overlapped members 10 and 10 of the body, and the overlapping members 13 and 13 which engage with the overlapped part 11 of the end member. The overla 'ipcd ends 10 and 10" of the body together with the web portion 13 and the overlapped flange members 13 and 13" project beyond the ends 11 and form an annular support of five thicknesses of metal to which a suitable header A of cast iron or other like material, is removably attached by means of the bolts 14. The headers serve to strengthen and give rigidity to the casing 10 but may be removed very readily by removal of the bolts 14-. Each header is pro- I gross sectional view takenon the line 4t-4 of vidod with a strengthening rib 15, and supported in a bearing 16 in one of the headers is a shaft 17 driven from any suitable source of power and adapted to rotate the inner cylinder. Upon one of the headers is formed a pair of bosses 18 designed to support mechanism (forming no part of the present invention and not herein illustrated) by which the direction of rotation oflthe inner cylinder is reversed at interva s.

The inner cylinder, which is revolved by the shaft 17 is designated 19, a fragment only of this cylinder being shown in cross section in Fig. 3. The cylinder 19 wherein the articles to be washed are placed and subjected to the action of wet steam, is provided with a plurality of perforations 20 through which steam (or water if desired) may pass in either direction.

One of the important features of my invention relates to the manner of preventing as shown in Fig. 3.

bent upon itself as at 12 and is then bent in leakage of steam out of the casing 10 when the cover 12 has been closed by means of the handle 21. The cover is slidablein curved guides 22 secured to the periphery of the casing 10, and the edge which engages the edge of the casing 10, is preferably formed The cover 12 is first the reverse direction as at 12 then is carried along to form the substantially straight web 12, then again bent upon itself as at 12 and finally terminates in the hook like end 12 The edge of the cover, formed as just described, is intended to engage, and cooperate with, the suitably formed edge of the casing 10 to prevent leakage of steam therefrom. The edge of the casing 10 is bent upon itself as at 10 then carries along as a straight Web portion 10 and then bent as at 10 to form a wall parallel to the Wall 10. When the cover is. closed down on the casing the space between 12 and 12 is occupied by the thicknesses of metal 10 and 10, the, space between 10 and 10 is occupied by the portions 12 12 and 12 and the hook shaped end 12 lies over and engages the upper edge of the wall 10 in this manner forming an interlocking joint past which steam cannot escape. It will, of course, be understood, that the casing 10 is but onehalf a cylinder, the cover forming the other half, and that, although not illustrated in the drawing, the edges of both casing and cover opposite those shown in the drawing are constructed similarly to the illustration of Fig. 3 so that a leak proof joint is provided at both edges of the cover and caslng. The entire structure is usually supported on legs 23 resting on the floor 24:.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is A washing machine casing,- embodying therein a substantially cylindrical sheet metal body portion having the material at the ends thereof doubled upon itself there being a space between the two layers of material, a circular sheet metal end member set in from each extremity of the body portion, the edge of each end member adjacentthe body portion being bent on itself to form two layers of material spaced from each other, a locking member for securing each end member to the body portion, each of said locking members comprising an angular. sheet of metal having its opposite ends bent upon themselves whereby one of said ends engages between the spaced layers of material of the end member and the other end engages between the spaced layers of material of the edge of the body portion,

and an annular cast metal headersecured'to' said body portion immediately adjacent and on the outer side of one of the end members. In testimony whereof I have aifixed my signature in presence of two witnesses.
